Outspoken rapper Killer Mike saw an interview that he did with the National Rifle Association’s TV network — in which he advocated for gun rights for black citizens — aired on the network during March for Our Lives on Saturday, giving the impression that he was opposed to the march.

He clarified the situation in two Instagram posts on Sunday night, leading with a Senegalese proverb that “there can be no peace without understanding” and citing inspiration from Martin Luther King, he said that he sat for an interview with “people who I might not always agree with,” the NRA, about black gun ownership. “That interview was used a week later by NRA-TV to disparage a very noble campaign that I actually support, March for Our Lives.

“I want to say I’m sorry, guys,” he continued. “I’m sorry that an interview I did about a minority — black people in this country — and gun rights was used as a weapon against you guys. That was unfair to you and it was wrong… As you ally, and I am your ally, I want to say that many of the people I organize with were at that march. … I am an ally and an advocate for you always.”
